Hi Wilmot residents. Let's talk fuel injectors. A fuel injector is a valve that delivers fuel to a vehicle's engine. It has to deliver the precise amount of fuel to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.Vehicles have one fuel injector for each cylinder in the engine. Your vehicle's control computer constantly monitors the engine and various sensors in the vehicle.  It also adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle's engine. Because fuel injectors are such precision instruments, dirt and contaminants are a serious detriment ... read more

The price of gas in NH has got people in Wilmot talking. It seems that Wilmot folks who need a bigger vehicle to carry family and gear, or provide four wheel drive, are hit especially hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy. First let's start with how we drive around NH. People in Wilmot may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts - you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don't drive with one foot on the brake. That's also a drag on fuel economy, and it wears out your brakes faster, too. Another thing Wilmot drivers can do is drive more slowly - but only when it's safe. Sometimes on the freeway we drive an extra five ... ten ... read more

Many Wilmot drivers have found themselves in the following situation: They go to get their oil changed and their friendly service advisor at Walker Automotive recommends a new engine air filter. They say yes, but don't know what an air filter is or what it does.If this has happened to you, rest assured that you did the right thing by getting a new one. But you should never be too embarrassed to ask your Walker Automotive service advisor for more information. It's your vehicle and you have a right to understand what you're paying for.Let's review: "What does an air filter do?"Air is the focus of this discussion. What is the air like outside in Wilmot right now? Can you see any smog? Is it full of pollen? How about dust? Anyone in NH with hay fever can tell you that there's plenty in the air that you can't see. Well, the engine air filter's job is to clean that air before it goes into your vehicle engine, to mix with the fuel and be burned. Without an e ... read more

Wilmot residents know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air—and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same . The turbocharged version delivers 350 horsepower.Why the big difference in power? Direct inj ... read more

The function of the fuel filter is pretty self-explanatory. It filters your fuel. The fuel filter is in the fuel line somewhere in between the fuel tank and the engine. Both gas and diesel vehicles around Wilmot use fuel filters. For more information about your fuel filter, visit Walker Automotive at 3 Deerwood Drive in Wilmot, NH 03287.Please call 603.526.4848 to make an appointment. Generally speaking there's not a lot of dirt in our Wilmot area auto fuel supply, but there is enough that you want to screen it out. The problem actually gets worse the older your vehicle becomes. That's because dirt, rust and other contaminants will settle out of the fuel and onto the bottom of the fuel tank. After your vehicle is five years or older, it can actually have a fair amount of sediment built up.That just means that the fuel filter has to work harder as your vehicle ages. It'll get clogged sooner and need to be replaced more often.A symp ... read more

For those of you in Wilmot, NH who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same fuel economy. The turbocharged version makes over 350 horsepower.So what are the differences from a conventional engine?The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it's then drawn into the engine with the air.With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder dur ... read more

No one in Wilmot, NH, likes to spend a chunk of change at the gas pump. Rising NH fuel prices, however, have spurred Wilmot drivers to focus on how to improve their fuel economy. North Americans literally drive billions of miles/kilometers less each month during times of high fuel prices. But we still need to drive (we love our vehicles, after all!), so it makes sense to try and increase our fuel economy however we can.Let's look at a real life example. This man has one of those really big SUVs. Lots of kids and horses to haul around, you know. His family was planning a four day camping trip. Here's what he did to cut his fuel costs:First, he installed a new, high flow engine air filter. Then he had his service center change his oil, flush his cooling system and service his front and rear differentials along with the transfer case. He also had a fuel system cleaning, replaced his PCV valve and breather element. He also made sure his tires were up to th ... read more

There's not much we can do about the price of gas in Wilmot, NH, but we do quite a bit about how much we use as we're driving on our Wilmot streets.Our driving habits can dramatically affect our fuel economy.The first thing we can do is watch the 'go-pedal.' Hard acceleration just sucks the gas. Gently leave stop lights and plan lane changes so you don't need to floor it. That can save you hundreds of dollars a year.Go a little slower on the freeway. Once you're going more than 65 miles an hour (105 kilometers per hour), your fuel economy starts to drop dramatically. Leave early so you don't need to rush to be on time. And cruise control is your friend – steady speed uses less gas.Plan errands ahead. Make fewer trips by combining errands.Hey at current gas prices, a lead-foot might as well be a gold foot.

Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the vehicle engine.Wilmot auto owners don't need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better your vehicle engine will run.Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your vehicle ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.The harder your fuel filter works, the more often it needs to be replaced. Check with your owner's manual to find out how often it should be serviced and how long you can expect it to last. Wilmot ... read more
